| Objective To study the aluminum alloy Micro Arc Oxidation (MAO) technology in the application of product protection in three aspects. Methods Four different brands of commonly used aluminum alloy structure materials were selected for MAO treatment, and the performance indices of the MAO coatings of the aluminum alloy, such as composition and appearance, hardness and wear resistance and corrosion resistance, were determined through a variety of detection means, and were compared with those of the hard anodic oxidation technology.Resultsthe thickness of the MAO film layer was 20~120μm, the hardness（HV）of the dense oxide film layer was greater than 900, the abrasion resistance of dense layer and wear rate were less than 10-4mm3/N·m, the salt spray test time was more than 96h, and the humid heat test time was more than10cycles, indicating that the performance was better than that of the hard anodic oxidation film membrane layer. Conclusion The MAO technology can greatly improve the abrasion resistance and corrosion resistance of aluminum alloy, and can thus be applied to improve the product performance in the three aspects of prevention. |
